More on installing 32bit applications on 64bit Debian Linux

While downloading the free, for private use, edition of Teamviewer for Linux, I found this How do I install TeamViewer on my Linux distribution? where in the section for Debian, Mint, Ubuntu, Kubuntu, Xubuntu… I found a simple way for the installation of 32bit packages on 64bit Debian.

For the 32-bit package:

sudo dpkg -i teamviewer_linux.deb

In case “dpkg” indicates missing dependencies, complete the installation by executing the following command:

sudo apt-get install -f

For this to work, of course, you need multiarch-support.

In the same page is also explained why the 64bit precompiled packages, cannot be installed on multiarch systems.

Notes to Multiarch:

On newer 64-bit DEB-systems with Multiarch-support (Debian 7) teamviewer_linux_x64.deb cannot be installed because the package ia32-libs is not available anymore on these systems. In this case you can use teamviewer_linux.deb instead.

In case you get the error “wrong architecture i386” you have to execute the following command lines:

  • dpkg --add-architecture i386
  • apt-get update

How to find and install needed 32bit libraries on an 64bit Debian Linux

Suppose that you have a 64bit (amd64) Debian Linux, and you want to run a 32bit application, that needs a library that, even though it appears installed on your system, the application cannot find it. The problem is that the library on your system is a 64bit one, but the application needs a 32bit one.

For example Android adt needs the 32bit, even when you download the 64bit archive (as of today), Second Life needs a lot more, being a 32bit application.

Popup Menus in Groovy

While trying to figure out how to create a Popu Menu in Groovy, I started my search from google searching for PopupMenu, JPopupMenu tutorial etc. Some of the results were the very good tutorial How to Use Menus in Java and the An example of the JPopupMenu in action, but it was not easy to translate/rewrite the Java examples in Groovy.

Searching about popup menus and groovy gave no fruits.

Editing Groovy with the Κate editor

Some time ago I stumbled upon Groovy.

Groovy is a relatively new language. It is an agile dynamic language for the Java Platform with almost-zero learning curve for Java programmers.

Someone said that Groovy is a super Java. It’s a laconic and powerful language with closures, builders, support for unit testing and mocking out-of-the-box. It can use any Java class or library and can be used anywhere Java can be used.
